Thus, only level 30 and above can reach 100 liveliness due to fishing and dungeon constraint and lack of salvage rope. However, even if you are level 30, not forgetting that warship upgrade costs 800k stones, it is unworthy to actually reach 100 liveliness in terms of silver cost vs benefit.
Not forgetting also that aptitude costs a lot of prestige and prestige is more worthy to use on aptitude. Thus, it is better for us to actually just hit 50 liveliness at this stage.
But, 400k for 1 salvage rope and 5 vitality. Vitality is priceless X)
But, everyday 1 rope, so on the 5th day, you will have 5 ropes so you can try hit 100 liveliness by salvage undersea treasure when you still haven't reach level 50.
When level 50, you can go shadow shop, so you can replace the aptitude task with it.
When level 60, you can do dungeon for both level 40 and 60.
